After a few searches in these forums I have only a question:

is there any beta driver for purevideo hd hardware decoding on 8500GT under XP?

thank you

I don't believe that any of the beta drivers support H.264 decoding in XP yet, only in Vista. Supposedly the XP driver for hardware H.264 decode will be coming out some time in June.

As much as I want it, I'm not holding my breath for Purevideo HD being included in a June XP driver release (as nvidia posted here):

http://www.nvidia.com/object/purevideo_hd_faq.html
What operating systems are supported by PureVideo HD technology?
The 32-bit versions of our ForceWare drivers for Windows XP and Windows Vista™ feature PureVideo HD. Please note that support of the PureVideo HD technology for the GeForce 8500 and GeForce 8600 GPUs will be limited to Windows Vista at launch. Support of the PureVideo HD technology for these GPUs under Windows XP will be added in upcoming ForceWare driver updates around the June 2007 timeframe . PureVideo HD support is not currently available for 64-bit operating systems.

Certainly hope I'm wrong ;)

That sucks. PureVideo HD support not available for 64-bit OSs. :thumbdwn:

Yes there is. Forceware 165.01 beta supports PureVideo 2 under XP. I only just found out last night and it's been out for over a month.

These were the ones that were assumed to be older than 160.03 due to the compile dates (and yes, others noted the driver versions being odd and some theories behind that).

I've been using 165.01 for 3 weeks and have seen zero improvement with CPU usage with h.264 using the latest WinDVD and PowerDVD codecs with "hardware acceleration" / DXVA support enabled in XP.

If you have some comparisons that show it is using hardware acceleration for HD content, then please, we would appreciate a description of the test and the results.

Purevideo hardware decoding is available for me using PowerDVD 7.2. Playing a quick video file of King Kong h.264 at 1080p has CPU utilization hovering around 30%. Not bad for no VDP2. ;) I'm using drivers 158.22 for WinXp.

8500/8600 cards should get even lower.

opps.. duplicate post.

We are talking about the 8500/8600 h264 acceleration in this thread and how it isn't working (yet).
I'm using PowerDVD 7 and see no CPU difference between the 160.03/165.01 and the official 8500/8600 drivers.

The legacy acceleration is working, just not HD acceleration on 8500/8600.

If there is some other test that shows it, I would love to try it.

FOR 8500/8600 h264 acceleration in WINXP

You must use
FORCEWARE 165.01 and
powerdvd 7.3 2911

If you don't use powerdvd player
You must set your player to use powerdvd 7.3 2911 h264/avc decoder
And you must play your video in VMR9 renderer.(overlay don't work)

It works fine for me with an 8600 GTS, Sempron 3400 (2.0 GHz) and PowerDVD Ultra 7.3 with the latest patch available here:

http://www.cyberlink.com/multi/download/dl_patch_397_112_ENU.html

http://www.cyberlink.com/multi/download/patches_112_ENU.html

" * Support nVidia GeForce 8500/8600 series hardware decoding
* Support ATI X2000 series hardware decoding"


I can playback Quicktime 1080p clips with 7% CPU utilisation (Transformers 1080p full trailer and many others). Down from 100% without any acceleration (50-90% with 7600 GT).
